2. Maximum peak total DC output power should not exceed 572W.
3. Peak power and current loading should be supported for a minimum of 1 second.
4. +3.3V, +5V and +12V DC output voltage should be within Figure 1 cross loading
range to meet regulation.
5. Ripple and Noise measuring with an oscilloscope with 20 MHz bandwidth in
Figure 1 cross loading range. Output should be bypassed at the connector with
a 0.1uF ceramic disk capacitor and a 10uF electrolytic capacitor to simulate
system load.The length of ground wire on probe should not longer than 40mm,
if a Non - differential type of scope was used.
2.1 CROSS REGULATION
The +5V & +3.3V combined load and +12VDC load shall remain within the defined
in section 2.0 over cross load combinations shown Figure 1:
2.2 HOLD-UP TIME: 16ms (minimum)
Test Condition: Full load. AC input 115V or 230V, 47Hz.
2.3 LOAD TRANSIENT RESPONSE (STEP LOAD)
Step load changes up to 60% (12V) and 30% (3.3V and 5V) of full load, while
other loads remains constant within the rating. The load waveform shall be a
square wave with the slope of the rise and fall at 1.0A/usec and the frequency
shall be from 50Hz to 10kHz. The DC output voltage will stay within regulation
of ±5% during the step load changes.

2.4 OVERSHOOT
Overshoot at turn on or turn off shall be less than 10% of the nominal output
voltage.
2.5 TIMING, HOUSEKEEPING AND CONTROL
A low active PS-ON (DC ON/OFF) input signal is equipped, which provide the
interface ENABLE or to DISABLE the GROUP1 of DC output. This signal is
electrically to interface with TTL,OPEN COLLECTOR and the HARD SWITCH.

Max Ripple/Noise: 400mV pk-pk. (no capacitor test)
3.0 OUTPUT PROTECTION
3.1 TOTAL POWER PROTECTION: (OPP )
Total power 150% max with shut-down and latch off protection.
3.2 OVER VOLTAE PROTECTION: (OVP)
3.3 SHORT CIRCUIT PROTECTION: (SCP)
The short between any output of group 1 will shut down all group1.
The short at group 2 will Shut down both group 1 and group 2.
3.4 OVER CURRENT PROTECTION: (OCP)
Over current protection was designed to limit the current to operate within safe
operating conditions.Total current 160% max with shut-down and latch
off protection.
3.5 OVER TEMPERATURE PROTECTION: (OTP)
This power supply include an over-temperature protection sensor, which can trip
and shut down the power supply at a preset temperature point. Such an
overheated condition is typically the result of cooling fan failure or excessive
maximum operation temperature.
3.6 NO-LOAD SITUATION
No damage or hazardous condition should occur with all the DC output
connectors disconnected from the load. The power supply may latch into
the shutdown state.

3.7 RESET AFTER SHUTDOWN
Whenever the power supply latches into shutdown state due to fault condition on
its output, the power supply will return to normal operation only after the fault has
been removed and the PS_ON# has been pulled low again. If the power supply
latches into shutdown state due to fault condition on 5Vsb, the power supply will
return to normal operation only after the fault has been removed and the power
switch (power cord) has been cycled off/on (plugged out/in) with A MINIMUM
OFF TIME OF 3 SECONDS.
